My parents think bjj is gay

When i convinced my parents to start going to bjj with one of my friends around a month ago they probably thought it was some striking martial art like taekwondo or karate (neither of them watch mma or bjj). Everytime that i would come home from practice at the start they would ask me to show them what we learnt and progressively they got the hang of what the sport is. My dad would also started to want to be a dummy less and less and when i would ask to show him something most of the time he said he was busy or made up some other excuse. Every time bjj would come up in conversations he would always mention that its not what he thought it was or that it is weird.
Yesterday my dad came up to me and asked me "hows it going with the girls" and we had a little awkward conversation. He insisted that since valentine was coming up he could give me a big budget to spend on gifts and other expenses. Now i lowkey have 0 game right now since im locked in for school (semester ends soon) and i kind of sugarcoated it but i told him the truth which probably made him even more suspicious. Recently my dad has commented on the way i dress and has even told me its feminine. I think i dress like a normal teen but my dad is too disconected from the youth to recognize it.
I should also say that i live in an eastern european country and everyone here is homophobic and racist etc. The oldheads in the server that share this experience give me advice
